DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Technical solutions in the embodiments of the present application willbe described clearly and thoroughly hereinafter with reference to theaccompanying drawings. Apparently, the embodiments described herein aremerely parts of but not exclusive embodiments of the presentapplication. All alternative embodiments obtained by those skilled inthe art based on the embodiments of the present application withoutcreative works shall fall within the protection scope of the presentapplication.

The First Embodiment

Referring to FIG. 1, an atomizer includes a housing assembly 10, anisolating assembly 20 and an atomizing assembly 30. The isolatingassembly 20 is positioned within the housing assembly 10, and an airintake passage 22 is formed between the isolating assembly 20 and thehousing assembly 10. The atomizing assembly 30 is positioned within theisolating assembly 20, and a liquid storage chamber 23 is formed betweenthe atomizing assembly 30 and the isolating assembly 20. Therefore, theisolating assembly 20 can effectively isolate the air intake passage 22from the liquid storage chamber 23, to avoid an interference between theair intake passage and the liquid storage chamber, thereby improving anoperational reliability of the electronic cigarette.

Specifically, the housing assembly 10 includes an upper cover 17, afirst external sleeve 241, and a bottom cover 245. The upper cover 17and the bottom cover 245 are positioned on the upper end and the lowerend of the first external sleeve 241, respectively. As shown in FIG. 1,the first external sleeve 241 defines an air intake hole 11 at an upperend of the first external sleeve 241, the air intake hole 11 fluidlycommunicates with the air intake passage 22, for air intake. Because theair intake hole 11 is positioned on the upper end of the first externalsleeve 241, thus, even when the liquid in the liquid storage chamber 23is leaked into the air intake passage 22 by gravity, the liquid gathersin the bottom cover 245, and does not leak out from the air intake hole11. The bottom cover 245 is provided with an assembly protrusion 359 atan upper end of the bottom cover 245, the assembly protrusion 359protrudes upwardly along an axial direction of the atomizer.

It should be noted that, the bottom cover 245 can be detachablyassembled. If the atomizer breaks down, when the bottom cover 245gathers a predetermined amount of leaked liquid, user can disassemblethe bottom cover 245 to clear the liquid.

Alternatively, the housing assembly 10 further includes a mouth piece 18positioned on an upper end of the upper cover 17. The mouth piece 18 canalso be omitted. User can directly suck on the protrusion of the uppercover 17.

In the illustrated embodiment as shown in FIG. 1, the isolating assembly20 includes a first internal sleeve 247 within the first external sleeve241, the air intake passage 22 is formed between the first internalsleeve 247 and the first external sleeve 241, such that, airflow entersthe atomizer via the air intake hole 11, and flows into the atomizingassembly 30 via the air intake passage 22.

In the illustrated embodiment as shown in FIG. 1, the atomizing assembly30 includes an atomizing sleeve 31 and an atomizing head 35. Theatomizing sleeve 31 is a hollow structure having two openings atopposite ends, and substantially has a trumpet shape. The atomizingsleeve 31 is positioned within the first internal sleeve 247, the upperend of the first internal sleeve 247 resists the upper cover 17, thelower end of the first internal sleeve 247 resists the lower end of theatomizing sleeve 31, (specifically, the lower end of the first internalsleeve 247 resists a trumpet opening of the lower end of the atomizingsleeve, the trumpet opening opens outwardly). Therefore, the atomizingsleeve 31, the first internal sleeve 247 and the upper cover 17 formsthe liquid storage chamber 23 cooperatively. In order to improve anair-tightness between the atomizing sleeve 31 and the first internalsleeve 247, a sealing member (not shown) is positioned between theatomizing sleeve 31 and the first internal sleeve 247. The upper end ofthe atomizing sleeve 31 is connected to the upper cover 17. The lowerend of the atomizing sleeve 31 is connected to the circumferentialsurface of the assembly protrusion 359. The atomizing sleeve 31 forms anatomizing chamber 244 in the inner chamber of the atomizing sleeve 31.The atomizing chamber 244 fluidly communicates with the mouth piece 18.The atomizing head 35 is positioned in the atomizing chamber 244, andthe lower end of the atomizing head 35 is connected to the internalcircumferential surface of the assembly protrusion 359. The smoggenerated by the liquid which is atomized by the atomizing head 35 canflow out via the atomizing chamber 244, and the mouth piece 18, for userto suck on.

The atomizing head 35 includes a supporting pipe 351, a liquid guidingmember 352, a heater 353, and an electrode contacting member 354electrically connected to the heater 353. When the supporting pipe 351is assembled in the atomizing sleeve 31, the lower end of the supportingpipe 351 is connected to the internal circumferential surface of theassembly protrusion 359. The liquid guiding member 352 is sleeved on theheater 353, the supporting pipe 351 is sleeved on the liquid guidingmember 352, the internal circumferential surface of the liquid guidingmember 352 abuts the heater 353, the circumferential surface of theliquid guiding member 352 abuts the supporting pipe 351. The atomizingsleeve 31 defines a liquid intake hole 311, the supporting pipe 351defines a liquid passing hole 355, thus the liquid in the liquid storagechamber 23 flows to the liquid guiding member 352 via the liquid intakehole 311 and the liquid passing hole 355. The heater 353 can be drivenby the electric to heat up the liquid in the liquid storage chamber 23to form the smog. The electrode contacting member 354 is positioned onthe lower end of the supporting pipe 351, the electrode contactingmember 354 passes through the assembly protrusion 359 and extends intothe bottom cover 245. An insulating member (not labeled) is positionedbetween the electrode contacting member 354 and the supporting pipe 351.The electrode contacting member 354 defines a ventilation hole 356fluidly communicating with the atomizing chamber 244. The bottom cover245 defines a ventilation groove 243 which fluidly communicates with theair intake passage 22 and the ventilation hole 356. Outside airflowflows into the atomizing chamber 244 via the air intake hole 11, the airintake passage 22, the ventilation groove 243 and the ventilation hole356. The airflow is mixed with the smog and flows out from the mouthpiece 18 for user to suck on. Because the outside airflow flows into theatomizer via the lower end of the atomizing chamber 244 and flows outfrom the upper end of atomizing chamber 244, the airflow flows throughthe whole atomizing head 35; thus, the outside airflow can completelycarries the smog generated from the liquid which is atomized by theatomizing head 35, the flavor is improved, a waste of the smog isavoided. Thus, the following situation can be avoided: when the smogcannot be carried out completely, the residual smog is condensed to formliquid after the electronic cigarette is disused, and causes theatomizing chamber 244 to produce liquid accumulation. Further, even ifthe liquid accumulation is formed, user can disassemble the bottom cover245 to clear the liquid.

The Second Embodiment

The second embodiment provides another atomizer, the specific structureis illustrated as follows:

Referring to FIG. 2 through FIG. 6, the atomizer includes a housingassembly 10, an isolating assembly 20 and an atomizing assembly 30. Theisolating assembly 20 is positioned in the housing assembly 10, and anair intake passage 22 is formed between the isolating assembly 20 andthe housing assembly 10. The atomizing assembly 30 is positioned in theisolating assembly 20, and a liquid storage chamber 23 is formed betweenthe atomizing assembly 30 and the isolating assembly 20. Therefore, theisolating assembly 20 can effectively isolate the air intake passage 22from the liquid storage chamber 23, to avoid an interference between theair intake passage and the liquid storage chamber, thereby improving anoperational reliability of the electronic cigarette.

The difference between the first embodiment and the second embodiment isthat, in the second embodiment, beside the upper cover 17, the firstexternal sleeve 241, and the bottom cover 245, the housing assembly 10further includes a second external sleeve 27. Besides the first internalsleeve 247, the isolating assembly 20 further includes a second internalsleeve 26. Besides the atomizing sleeve 31 and the atomizing head 35,the atomizing assembly 30 further includes a ventilation pipe 25. Anadditional air intake passage 221 is formed between the second internalsleeve 26 and the second external sleeve 27. An additional liquidstorage chamber 211 is formed between the second internal sleeve 26 andthe ventilation pipe 25. The second internal sleeve 26 is positioned onthe upper end of the first internal sleeve 247, the second externalsleeve 27 is positioned on the upper end of the first external sleeve241, the ventilation pipe 25 is positioned on the upper end of theatomizing sleeve 31, thereby causing the additional air intake passage221 to fluidly communicate with the air intake passage 22, causing theadditional liquid storage chamber 211 to fluidly communicate with theliquid storage chamber 23, The lumen of the ventilation pipe 25 fluidlycommunicates with the atomizing chamber 244. Therefore, when user expectto increase the liquid storage volume, the second internal sleeve 26 andthe ventilation pipe 25 can be assembled, thereby the additional liquidstorage chamber 211 can be obtained. At the time, the user can furtherassembly the second external sleeve 27 for improve an integrality of theappearance of the atomizer.

Referring to FIG. 12 and FIG. 13, the first internal sleeve 247 isprovided with a plurality of protruding flanges 248 at an externalsurface of the first internal sleeve 247. The protruding flange 248extends along an axial direction of the first internal sleeve 247. Thenumber of the plurality of protruding flanges 248 is at least two, theplurality of protruding flanges 248 are uniformly disturbed on thecircumferential surface of the first internal sleeve 247. The pluralityof protruding flanges 24 are spaced from each other. Every two adjacentprotruding flanges 248 forms a ventilation recess 249 there-between, theair intake passage 22 is formed between the ventilation recess 249 andthe first external sleeve 241. The protruding flange 248 tightly engagesthe first external sleeve 241 for fixing the first internal sleeve 247.The upper end of the first internal sleeve 247 is provided with a dome246, the external circumference of the dome 246 is provided an assemblygroove 2462, the assembly groove 2462 is arranged along thecircumferential direction of the first internal sleeve 247. The centerof the dome 246 defines an assembly hole 2461 and a liquid passinggroove 2463, the liquid passing groove 2463 is positioned between theassembly groove 2462 and the assembly hole 2461. The second internalsleeve 26 extends into the assembly groove 2462. Alternatively, when thefirst internal sleeve 247 is processed, the protruding flange 248 can beformed on the first internal sleeve 247 by injection molding orstamping.

Referring to FIG. 5 and FIG. 6, the atomizing sleeve 31 has asubstantially convex shape. The upper end of the atomizing sleeve 31extends into the assembly hole 2461, the ventilation pipe 25 extendsinto the upper end of the atomizing sleeve 31, for the lumen of theventilation pipe 25 to fluidly communicate with the atomizing chamber244. The atomizing head 35 is positioned in the atomizing chamber 244,and specifically positioned on the lower end of the atomizing sleeve 31.The liquid storage chamber 23 and the additional liquid storage chamber211 are communicated with each other via the liquid passing groove 2463,causing the liquid in the additional liquid storage chamber 211 to flowinto the liquid storage chamber 23 via the liquid passing groove 2463,thereby accomplishing a replenishment for the liquid storage chamber 23.In the illustrated embodiment, in order to facilitate for user toobserve the liquid volume in the additional liquid storage chamber 211,in order to timely supply the liquid, the second internal sleeve 26 andthe second external sleeve 27 are made of transparent or translucentmaterials, for example, the material is glass. Accordingly, in the firstembodiment, the first internal sleeve 241 and the first internal sleeve247 are made of transparent or translucent materials, facilitating foruser to observe the liquid in the liquid storage chamber 23.

The difference between the first embodiment and the second embodiment isfurther that, in the second embodiment, the atomizing head 35 has astructure different from that in the first embodiment.

The heater 353 is wound about the liquid guiding member 352, andopposite ends of the heater 353 are fixed to the assembly post 358.

Because the structure of the atomizing head 35 is different from that inthe first embodiment, therefore, the matching mode between the atomizinghead 35 and the first internal sleeve 347, the atomizing sleeve 31 andthe bottom cover 245 is different from that in the first embodiment.

Specifically, the assembly seat 357 includes a first isolating plate 333and a second isolating plate 332. Both the first isolating plate 333 andthe second isolating plate 332 extend outwardly along a radial directionof the assembly seat 357.

The upper end of the assemblyseat 357 defines a liquid intake groove 32 fluidly communicating with agap 334 between the first isolating plate 333 and the second isolatingplate 332. Opposite ends of the liquid guiding member 352 are latched inthe liquid intake groove 32. Therefore, the liquid in the liquid storagechamber 23 flows into the gap 334 between the first isolating plate 333and the second isolating plate 332, and can be absorbed by the liquidguiding member 352 which is clamped by the liquid intake groove 32. Theassembly seat 357 further defines an air passing hole 34 extending alongan axial direction of the assembly seat 357, the air passing hole 34cuts through opposite ends of the assembly seat 357. The air passinghole 34 fluidly communicates with the atomizing chamber 244 and the airintake passage 22.

The assembly seat 357 is provided with a connecting post 36protruding from a lower end surface of the assembly seat 357. Theconnecting post 36 protrudes downwardly along an axial direction of theassembly seat 357. At least a part of the connecting post 36 extends outof the bottom cover 245, the part of the connecting post 36 extendingout of the bottom cover 245 is provided with a plurality of externalthreads which is configured to engage the battery assembly.

Specifically, the first positioning member 331 is a positioningcutout on the second isolating plate 332, the second positioning member28 is a positioning protrusion on the first internal sleeve 247, thepositioning protrusion latches in the positioning cutout, for limiting arelative rotation between the atomizing head 35 and the first internalsleeve 247.

In the atomizing head 35 in the illustrated embodiment, user can replacethe heater 353 and/or the liquid guiding member 352 by a self-reliance,and a dripping function can also be achieved, i.e. the liquid is notdripped into the liquid storage chamber 23 and the additional liquidstorage chamber 211, on the contrary, the liquid is directly dripped onthe liquid guiding member 352. When user want to achieve a liquiddripping function or replace the heater 353 of the atomizing assembly 30or replace the liquid guiding member 352 of the atomizing assembly 30,merely the bottom cover 245 is rotated to open, thus the atomizing head35 together with the bottom cover 245 can be taken down, therefore, aliquid dripping operation or an replacement operation can be performed,it is easy and convenient.

Not only that, the difference between the second embodiment and thefirst embodiment, in the second embodiment, the housing assembly 10further includes a connecting member 13 and an adjusting member 14, theair intake hole 11 is positioned on the connecting member 13, theadjusting member 14 is rotatably positioned on the connecting member 13to adjust an air intake volume of the air intake hole 11.
